Peptinov’s vaccine approach can be applied to many non-infectious diseases (auto-immune diseases, cancer, chronic pain). It has the potential to provide a complementary approach to monoclonal antibodies in large populations with limited access to biologics. The effect duration of Peptinov’s vaccines is temporary (3-4 months). Consequently the vaccines must be administered several times per year. Their production cost is very low.



Peptinov’s active inmmunization approach

Peptinov’s breakthrough active immunization approach uses tailored peptide-based vaccines, derived from target self proteins.

These peptides which are selected and designed using an array of bioinformatics tools (trade secret) are designed to induce the production of antibodies directed against the targeted proteins after immunization. The produced antibodies neutralize the biological activity of the target protein.

In doing so, Peptinov’s vaccines have a similar action compared to monoclonal antibodies.

This vaccine approach present several advantages:

  • very low production costs

  • ease of use

  • potentially no resistance to treatment.

Peptinov’s anti-IL-6 vaccine is the most advanced product in the R&D pipeline and is currently entering regulatory pre-clinical development (toxicology studies).
